If the sum of three consecutive terms of GP are k-4,k,k+5. Find k

labwork [276]

Answer:

k = 20

Step-by-step explanation:

t1 = a = k-4

a = k - 4

t2 = ar = k

(k-4)r = k - 4

r = k/(k-4)

t3 = ar^2 = k + 5

(k - 4)(k/k - 4)^2 = k+5

k^2/k-4 = k+5

k^2 = (k+5)(k-4)

k^2 = k^2 -4k +5k -20

0 = k -20

k =20

What is an equivalent to -16m^2n-(-25m^2n)+(-7m^2n)

pantera1 [17]

Answer:

The equivalent expression is:

$-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n$

Step-by-step explanation:

Given the expression

$-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a$

$=-16m^2n+25m^2n-7m^2n$

$\mathrm{Add\:similar\:elements:}\:-16m^2n+25m^2n-7m^2n=2m^2n$

$=2m^2n$

Therefore, the equivalent expression is:

$-16m^2n-\left(-25m^2n\right)+\left(-7m^2n\right)=2m^2n$
